I struggled with this for most of the day and it just didnt seem to work. Turns out it was my fault and when I run the program properly it does exactly what I wanted. Ive been seriously out of disk space for months and didnt know why. Turns out Dropbox is the culprit. My settings on Dropbox made it load everything on dropbox onto my hard drive as soon as I booted up. My hard drive was full and I didnt know why. With Disk Space I could finally see it. 400 GB of data being loaded on my computer. So I turned off automatic syncing and suddenly, my computer is running great. This was worth the price to find out what the problem was.
